Easiest way to mask characters in HTML(5) text input

Question

Does HTML5 have any kind of text field masking or do I still have to trap onkeydown etc.?

jbabey is right--\"masking\" as in blocking certain illegal ch

Answer 1

A little late, but a useful plugin that will actually use a mask to give a bit more restriction on user input.

<div class="col-sm-3 col-md-6 col-lg-4">
  <div class="form-group">
     <label for="addPhone">Phone Number *</label>
      <input id="addPhone" name="addPhone" type="text" class="form-control 
       required" data-mask="(999) 999-9999"placeholder>
    <span class="help-block">(999) 999-9999</span>
  </div>
</div>

 <!-- Input Mask -->
 <script src="js/plugins/jasny/jasny-bootstrap.min.js"></script>

Answer 2

Yes, according to HTML5 drafts you can use the pattern attribute to specify the allowed input using a regular expression. For some types of data, you can use special input fields like <input type=email>. But these features still widely lack support or have qualitatively poor support.

Answer 3

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

Answer 4

Use this JavaScript.

$(":input").inputmask();
$("#phone").inputmask({"mask": "(999) 999-9999"});

Answer 5

1. Basic validation can be performed by choosing the type attribute of input elements. For example: <input type="email" /> <input type="URL" /> <input type="number" />

2. using pattern attribute like: <input type="text" pattern="[1-4]{5}" />

3. required attribute <input type="text" required />

4. maxlength: <input type="text" maxlength="20" />

5. min & max: <input type="number" min="1" max="4" />
